Eustathius of Antioch

Eustathius of Antioch (died 360 AD) was Patriarch of Antioch from 324 to 337, succeeding Paulinus of Tyre and preceding Meletius of Antioch.

Biography
Eustathius was born in Side, Pamphylia, and he became Bishop of Beroea in 320 AD and Patriarch of Antioch shortly before attending the First Council of Nicaea in 325 AD. He led the second-largest bishopric in Christendom and was a very strong opponent of Arius, refusing to allow Arians to work as clergy in Antioch. In 330, he was deposed for adultery by the emperor, who was allied with his Arian enemies. He died in exile in Trajanopolis, Thrace in 360 AD.
